i have it set so my phone will unlock with my fingerprint instead of entering my 20-character password, but it only loving works once in a blue moon. i have it registered to all 8 of my fingers and both thumbs and it just never loving works. i've reprinted them like 4000 times and it still only works 1/10 of the time and just shakes and tells me to "try again". it's a pain in the ass to put in my password and i really wish i didnt have to use it. it's not even like i have deformed world war II survivor hands/fingers i just have normal fingers just work god damn it. it never works when my hands are clean or dirty or dry or wet or hot or cold or loving anything i might as well just use my loving toes forget. anyways could someone contact apple because this is bullcrap
